Application filed December 1, 1910. Serial No. 595,021.

To alt /w/wln 'it may concern Be it known that I, Josnn I-luNz, a subject ot the King ot Prussia, and resident ot Creteld, in the Province oit the Rhine, Gen man Empire, have invented certain new and usetul Improvements in CopWinding Machines, oit which the following is a specitication.

My invention relates to a machine designed tor winding thread onto a spindle` in which a rapid to-and-ro distribution ot' the thread is made over the built up conical end ot the cop in order to bind the coils together to prevent ravelin As this bnild ing up progresses the spindle, and its holder aremoved longitudinally so that the width ot the finished cop is siilbstantially that of the diameter et' the lease ot' the cone.

kip-winding machines. so tar as known to me, are subject to various detects which cause 'frequent breaking ot the thread, and moreover they are run at too low a speed to render them ecom'nnical.

The object ot the present invention is to provide a cop-winding machine which shall be simple, durable and capable ot ruiming at' the highest speed with minimum wear and liability to get out ot' order, and which is simple as to the control ot the thread and as to the operations ot its parts.

ertain features oit the invention relate to the driving mechanism by which all jar and shock are obviated in starting and stopping the machine.

Other features relate to an automatic knock-ott tor stopping the machine when a predetermined amount of thread has been wound and also when the thread breaks or is exhausted.

Other features relate to the manner of mounting the spindle by which it may be easily and readily handled for receiving and removing the cop or bobbin or cop tube.

In brief, the present invention consists in various details ot construction and arrangement ot' parts which go to make up a high speed, durable machine, which can handle the thread quickly and effectively and without sul'iviecting the same to shock and strain upon the reversal or traversing motion, and when starting and stopping the ma chine.

The invention will be understood by reterence to the accompanying` drawings in which-- ltignre l. is a sectional side elevation ot a machine constructed in accordance with the present invention; `Fig. 2 a front view of the same; Fig. 3 a view similar to Fig. 1 looking iti-om the opposite side ot the machine; Fig. `t a view similar to Fig. l showing the position ot' the parts when the thread breaks; Figs. 5, t3, 7, S, 9, l0 and 11 detail views ot various parts.

Similar reference numerals indicate similar parts in the several views.

.Referring to the drawings, l designates the trame oit the machine, which maybe of suitable form and proportions to sustain the operating parts; and 2 a swi't't ot. usual 'torni rotatably supported on the frame and 'ti-cm which the thread is delivered to the winding machine. lowcr 'tcr driving the machine is derived trom thc main shatt 3. belt lleading 'trom a pulley on said sha'lt drives a shatt mounted in suitable bearings on the 'trame l.

"he present machine compris-res as its essential elements a thread-guide: a verti cally mounted rotatable and lmigitudinally movable spindle; a conical rotatable member tor moving the spindle and the cop mounted thereon longitudinally as the cop becomes tillcd with thread: a driving mechanism by means ot which thc machine may be started with ease, and without an abrupt motion which would be liable to break the thread: and stop motions to stop the machine when a predetei-mined amount ot thread has been wound on the bobbin or cop. and when the thread breaks during the winding operation. l will now describe these several parts in detail.

'/m rein/Haq mech(misch-The thread may be wound directly on the spindle` or on a bobbin or cop tube placed on the spindle.y and in the tollmving description I use the term spindle in a generic sense to include all forms. The winding surtace may be ot the saine diameter throughout or provided with a cone head as shown in Fig. 3. The spindle is suspended vertically in a loose collar 't0 (sec Fig. 9), the latter having a laterally projecting ear l1 through which passes a pivot pin carried by a slide block 1iin the torni ot a yoke, as shown in Fig. 2.

The spindle is prevented from falling through the collar by a nut 13 on the upper end of the spindle, the said nut resting upon the collar 10. rllhe block 12 has mounted on its rear a roller 14 which travels in a vertical guide 15 mounted on the machine frame. The lower end of the spindle 7 is square or rectangular in section and lits loosely into a corresponding opening in a bearing sleeve 16, said sleeve being` suitably supported in a bracket 17, on roller bearings 13, as shown in Fig. 11. To eifect the rotation of the spindle 7, the sleeve 1G is extended downwardly and inside of the hub 19 on a pinion 20, the sleeve being secured to said hub by means of a set screw 21. The pinion 20 is driven by a spur gea-r 22 fast on a vertical shaft 23, the latter being supported in bearings carried by the machine frame and longitudinally movable therein. By making the lower or engaging end of the spindle square or rectangular in section l prevent slipping or turning of the spindle relatively to its seat.

The thread as it is deliveredfrom the swift 2 passes around a guide roll mounted on a swinging arm 25 pivoted on 26 carried by a keeper 40 hereafter described. From the roll 24 t-he thread passes through the slot 27 of the thread-guide, said guide being in the form of a drinn 23 fixed on the vertical shaft 23. The drum 23, as shown in the drawings, is in the form of a frustum of a cone and the peripheral. slot 27 therein is symmetrical with respect to the axis of the drum; that is, the slot extends obliquely upward from a central point, shown in Figs. 2 and 3, equally in both directions to its highest point diametrically opposite. The slot 27 is not on the path of a true spiral, the central portion of each half of the slot being substantially straight.

As the spindle is lilled with thread it is moved longitudinally by the cone roller 3 which is rotatably mounted on a bearing adjnstably supported in a bracket 29. The adjustment provided, as shown in Fig. 2, permits the angle of inclination of the bearing surface of the cone 3 to the spindle to be varied, as well as its position longitudinally to the cop cone.

The ZM/16mg mcczam'am.-The shaft 23 on which the drum 23 is fixed passes through suitable bearings in the machine frame, and has fixed to its lower end a bevel friction wheel 30 adapted to bear against a corresponding wheel 31 on shaft 5. The driven wheel 30 is held normally out of engagement with the driving wheel 31 by a weighted lever 32 pivoted at 33. The inner end of lever 32 carries a brake shoe 34 which bears against the under side of the driven wheel 30, the weight 35 on said lever and other parts to be described being sufficient to exert an upwardpressure on wheel 30 so as to raise it, and the shaft 23, out of frictional engagement with wheel 31. As the drum 23, spur gear 22, and wheel 30 are fast on shaft 23, it will be understood that when the parts are in their normal position, as shown in Fig. 4, all of said parts will be raised. To raise shaft 23 and parts carried thereby, l provide a rock shaft 36 which is adapted'to be moved by a hand lever 37, or by automatic knock-oli" mechanism. On the shaft 36 is a crank arm 33 (see Figs.v 4 and 7 and said arm is connected to lever by a vertical link 39. lhen the inner end of the lever 32 is depressed to release brake shoe 34 from engagement with wheel 30, the latter and shaft 23 and drum 23 will rest by gravity on driving wheel 31. This provides an easy, smooth running drive which can be thrown into and out of action with no shock or jar to the parts or to the thread. The operator is enabled to bring the two wheels 30 and 31 into engagement with each other gradually so that the drum 23 and spindle 7 attain their full speed without the shock attendant upon the use of ,gear drives.

Stopping 'medeweten-ln order to stop the machine after a predetermined length of cop has been wound, and also when 'the thread breaks, l have provided the following means: Un the rock shaft 36 is fixed a trip-lateh 40, which, in its normal position, is out of engagement with a keeper 41 fast on a pivot stud 42 extending from the machine frame, and held against the side of latch 40 by a spring 43. (Figs. 6 and 7). W hen shaft 3G is rocked to start the machine, the latch 40 is moved upwardly, and the keeper 41 being under spring tension, is moved under the end of said latch and holds the latter and shaft 36 locked against rotation until a predetermined amount of thread wound on the spindle, or until the thread Vadjustable cam 43 (Figs. 3 and 6) which is adapted to bear against the end of the pivot stud 26 to move the same and to thereby rock keeper 41 on its bearing 42 to release latch 40. As the block 12 is moved upwardly, the link 44, lever 45, and rod 47 will be raised and the cam surface 43, secured to rod 47, will bear against the pivot stud 26 according to the adjustment of cam 43; that is, said cam may be so adjusted as to release latch 40 for a predetermined length of winding.

.iioV

W hen keeper Lll is moved to release latch i-0, the weight 35 on lever 32 etli'ects the rocking ol shaitt 3G so as to bring latch ll-t) to the side ot keeper 4l. lhis movement also brings brake shoe 341; into engagement with wheel 30 and raises said wheel and shaft Q?) out oti engagement with the driving wheel 321. to suspend the rotation of the drum and spindle. As'above stated, camv 48 is made adjustable along its supporting rod 4l? to determine when the cani shall act on the pivot stud QG; that is7 the position oit cani 4S detern'iines the length of the cop. The thickness ot' the cop is determined by the position ot the cone S. I also provide means to stop the machine ii' the thread should break during the winding operation, or upon the exhaustion of the swift. rl`he tension on the thread during the winding is sullicient to hold up the outer end oit lever 25 which carries the guide roll 24k, said lever 25 being mounted on the pivot stud 26. On shal'ft QB is mounted a trip-cam t9 (see Fig. 5), and the end el lever is bent at right angles thereto, as at 51. Normally the inner end ot lever is below and out oit the path of cam llt). When, however, the thread breaks the outer end of said lever will drop and its inner end be brought into the path of cani llt) and as the toe 51 of said lever is struck by the cam the keeper 41. will be rocked on its bearing 41-2 to thereby release latch 41:() and permit the weight to rock the sha'tt Bti and to bring the brake shoe into engagement with the driven wheel 30. and to raise the shaft 23, and parts carried thereby, as betere described. To insure a positive 1nove ment of lever Q5 when the thread tweaks l provide the means illustrated in detail in Fig. S. This comprises a vertical rod stepped into a suitable bearing on the machine frame and surrounded by a casing 52 the rod 52 has secured thereto a sleeve ft having a la'ttally projecting bent' arm 55 extending tlnfeugh a slot in the wall ot' the casing 53. lhe sleeve 54. and its arm 55 are pref-sed downwardly by a spring 5G within the, casing'. The arm rests on lever 5213 and is held upwardly so as to slightly compress the spring 5G by reason ot the tension on the thread. A light spring` is used so that when the thread breaks the spring pressure will be just enough to insure a posi tive movement oit lever 25. ln order to prevent the inner end of lever 25 rising too high, I secure a flange 50 to shat't Q5 innnediately above the cam 49.

It a bobbin or cop tube is used, the spindle Ais raised and swung outwardly, as shown by the dotted lines in l" ig. 3. and a'l'ter placing' the bobbin or cop tubo thereon the spindle is replaced in its bearing in the sleeve 1,6. The machine is then started by the operator tin-ning the handle 37 so as to release the brake shoe 34 from engagement with wheel 30 and to permit said wheel to engage the driving wheel 311. ',lhe lever 32 may be lowered graduallyl so as to permit wheel 30 to engage wheel 3l without any shock or jar, the l'nll speed being attained when the entire weight oli' wheel tit), shail't. 23, gear 2Q and drain Q8 rests upon the driving wheel ill. It. the spindle is ,not provided with a coned head the thread is wound thereon until its thickness is such as to contact with the conieal member 8 which in close proximity to the head or upper end of the spindle. The conical member S will then compel the ormation ot a coned head oit thread on the spindle. In practice, however. .lV prefer to nui a bobbin or cop tube with a coned head. As soon as the thread is wound snlliciently to contact with the member 8 the pressure thereon will move the spindle longitudinally relatively to the drum QS, and such movew ment will continue until the machine is stopped either by hand, or automatically when a pretletermined amount is wound7 or whelrthe thread breaks or is exhausted. d

lt will be noted that the drum QS is adapted to deliver the thread back and 'lo'rth a predetermined distance ou the spindle less than the length ot" the Iinished cop, and that the ,spindle is moved longitudinall)7 relatively to the guide drnm 52S while the thread is being wound thereon. and that the drnln is moved relatively to the spindle when the martine is stopped trom any canse. 'lhis movement ol the drum, when the machine is stoppedg is etl'ected b v raising the lever 22? the. latter serving not only as a brake but as the means through which the driven wheel 210m and sha'lt i, and the parts carried thereby, are lilited ont ol engagement with the drivingl wheel ill. iv'hen tht` machine is running the engagement ot latch -ltl b v keeper -tl will prevent the rotation ol lsha'tt 3o and prevent thereby the stopping ot" the machine either manually or autonuitically 't'rom any ot' the causes bc'tore rel'errcd to,

'lhe employment ot a Irietion drivtl in the manner described is ol' advantage, not only in respect to ease otE starting and stopping witlruit shock or jalgbnt additionally in that. the wear o'l the driven member $5() does not intcrtcre with the propel' running o'll the machine-r and renewal thereo't is not' necessary until said member is wholly nntit ttor use.

.Ms belore stated, l may wind the thread directly on the spindle so as to produce an all-cop or I may wind on a cop7 butt cop or bobbin.
